batch.properties文件包含以下行：

use_memory_mapped_buffers=true
neostore.nodestore.db.mapped_memory=100M
neostore.relationshipstore.db.mapped_memory=500M
neostore.propertystore.db.mapped_memory=1G
neostore.propertystore.db.strings.mapped_memory=200M
neostore.propertystore.db.arrays.mapped_memory=0M
neostore.propertystore.db.index.keys.mapped_memory=15M
neostore.propertystore.db.index.mapped_memory=15M
batch_import.node_index.users=exact

当试图在Windows上运行批处理导入程序时，我遇到了以下异常：

*I:\Research\Temporal Analysy\neo4j>java-server-xmx4g-jar batch-import-jar-with-dependencies.jar data/graph.db nodes.csv rels.csv node_index users fulltext nodes_index.csv rel_index工作精确rels_index.csv*

Using Existing Configuration File

如果有人在windows机器上成功地将自动索引的数据导入到neo4j数据库中，我将非常感谢描述正确的过程。

谢谢！

首先，您必须指定要索引的csv列，以增加标题。例如，如果要索引的属性是name，则其标头应如下所示

name:string:chewbecca

调用索引的地方。丘贝卡。

其次，必须在属性文件中设置正确的索引名称。作为您的配置，您已经设置了以下内容：

batch_import.node_index.users=exact

batch_import.node_index.chewbecca=exact
